So I followed rom install instructions in OP and music sounds great when I play through the phone speakers V4A works. However, every time I use my headphones v4a stops working and just shows processing: No in the driver status. Any ideas?
Try wiping cache and dalvik and flash the boot.img of your current rom. Once you boot back up after optimizing apps go back into recovery and wipe cache and dalvik again then flash this kernel.
Can you check your supersu settings and look towards the bottom it should tell you if it's a system app or if it's running systemless
